We use the NRF Mesh Android Library (and are developing with iOS version as well). An issue that we are running into on a small number of devices is that the library things...
I'm starting a new design on nRF52 and I need to connect a microphone on it. Reading the datasheets and questions here, I found there's 3 solutions for the type of microphone...
Hi,
I was reading the procedure to prepare the NRF52 DK board for current measuring and some questions came into my mind. I understand we have to open the P22 so we interrupt...
I have set up raspberry pi 3 as a border router and programmed the the nrf51422 using the iot_ipv6_coap_server_pca10028 and could successfully switch on and off led3 and led4...

Can someone tell me how the DETECT signal works in the nRF52840?
This version of the nrf52 has 2 GPIO ports.
Does that mean there are 2 DETECT signals? or is there still...
Hello, I'm using the nrf UART 2.0 app with nrf51822 and I'm wondering how a line of characters is sent using this app. For example if I write 'abcdefg' does the BLE receive...

Hi, even if I set hal_nrf_enable_ack_payload(false) on the sender (and receiver), the receiver still sends back an ACK which i can detect in the NRF_ISR(). is this normal...
Hello,
I have a pca10028 and I am wondering if I can use it also to flash nrf52 boards.
I quickly tried with rknrfgo on mac to wipe a custom board based on nRF52832 and...
Hello.
I decided to use an external solution for RTC.
Sometimes the RTC chip offers an buffered 32.768KHz output.
Can I use this output to supply the 32.768KHz to the nRF52832...
